Arabelle Solutions is pleased to be supplying an SMR nuclear steam turbine, TOPAIR generator, and associated heat exchanger for the first GE Vernova Hitachi Nuclear Energy BWRX-300 small modular reactor project at Ontario Power Generation’s Darlington Nuclear Generating Station in Canada.
“We are proud to be delivering the main turbine hall equipment for the G7’s first SMR project. Leveraging our global engineering expertise, we have optimised our steam turbine generator modules for the SMR environment, underlining our strategy of providing turbine island solutions for any reactor type,” said Catherine Cornand, Chief Executive Officer, Arabelle Solutions.
The equipment will form key components of the Darlington SMR turbine island. Once operational, this SMR will deliver enough electricity for approximately 300,000 homes.
Cedric Couffignal, head of New Build at Arabelle Solutions added: “The 300 MWe-class steam turbine generator has been specifically engineered to operate under the steam conditions of the BWRX-300 SMR and the team has optimized the turbine island’s steam and water loop to enhance overall plant efficiency and maximize electrical output.”
The supply chain for the turbine hall will include specialist providers from Canada, including Ontario-based Chemetics Inc, which will manufacture components for the heat exchangers.
In total, the full-speed steam turbine generator shaftline for the Darlington SMR will be 34 metres long and includes a single-flow high-pressure module and two double-flow low-pressure modules to improve cycle efficiency. It will be coupled with an air-cooled TOPAIR generator rated up to 370 MVA for the 60 Hz Canadian grid.
